I just received the same SanDisk Ultra 64GB MICRO SDXC and I put it directly into my TF700t, without any formatting. The card is well recognized and pictures transferred on it are recognized by the "Gallery" application too. On the other hand have somebody be able to find any USB key supported by this Gallery application ?

SD Card Class = Class 10 or anything lower than that will work. (Polled from this thread)
SD Card Size: 128GB SD card or smaller will work. (As stated by many people on this very thread.)

Side note: Whoooooaaaa ! That's a lot of money for a SD card...
you could get an external HDD WAY WAY CHEAPER (For keyboard users, sorry tablet only folks)
~ Or use DROP BOX, GOOGLE DRIVE, ETC. FOR FREE

Sure you can use 64. Some members have reported using 128 successfully

i would be one of those not that i need the space. to the original poster, over the past year i have seen several have issues with sd cards of various capacities and formats that would work just fine for most but some have issues for others? if you can get any size sd card even a cheapo 2gb to work then you have removed the asus as being the likely source of the problem leaving just the card itself. just a thought but if you have the dock you can get a usb/sd card adapter/attachment. the ones i have were all included free when i got my sd cards online but i have seen them sold alone for less than two bucks. you could use that check or use that as another means to trouble shoot. that way you can check not only your sd card but also the asus sd card hardware, because if the card works by means of the adapter then odds are it is an asus hardware issue since the card works using the usb adapter. after all is said and done you can just use the adapter on those occasions you need to transfer data or don't have a reader on a pc but plenty of usb slots, for that matter if its just pics you can use the adapter and plug your sd card into the usb in a flat panel. they are very small, basically a little more than half the size of domino if that. amazon has them, newegg. or you could do as i did and get a card that comes with via amazon just need to read through the fine print to see if the card is bundled with the usb card adapter, a lot are. i'd just mail you one of my spares but the cost of mailing it on my part would be more than you just outright purchasing it.

Hi All,
I just finished reading this entire thread....I think I am more confused now than what I was when I first started. It seems that some people have had many issues but others have been pretty succesfull with using a 64gb card. Which card should I buy if I want to go with a 64gb card on the tablet? What has worked on the dock itself? I will probably buy the dock soon too.

Welcome to the forum!

I have a SanDisc 64GB UHS-1 card in the tablet and a 64GB Duracell card in the keyboard, both work fine...

Hi new Transformer owner here, just managed to get hold of a pre-owned TF201 which has been rooted and had Cyanogen Jelly Bean put on it. Am just about to order a 64GB card for it but wanted to check if anyone else has a similar modded one and had any problems using a 64gig card?
